Once you're branded a heretic, it's pretty impossible for people to accept you. Any Ishgardian that put their neck out on the line would be kind of ostracizing themselves from their own belief, not necessarily out in the open but perhaps in their own religion and kind of betraying Halone.
On a secondary note, there isn't some "big list of heresey" that they keep around in the upper echelons of their society. That's why they have Inquisitors always about and making sure that everything is kept in check. Hell, there's even the Dark Knights to worry about, upholding the justice among all social ranks and classes of Ishgard. Once you are branded a heretic, you are fairly certain to never be accepted once again into the fold. Especially if you're of the higher echelon, which is the caste of people that live that very comfortable life. You wouldn't suddenly just appear and get everything you used to have without the entirety of the Clergy looking at you and laughing at you before dragging you off to some sort of penance, or worse.
My recommendation wouldn't be to take this route but instead to take the route of Ishgard needing able bodies to add to the war effort. Something that is very real and very much going to be happening. Rather than saying, "Look, I really just want my kush life back," say something to the effect of, "I've pledged my life, body, and soul to The Holy See in terms of penance and am willing to do anything to earn the graces of my people once again." As you're an Elezen and as you talked about your character wanting their kush life back, considering that would make them of the higher caste of people in Ishgard, it's a little more believable taking that route with an Inquisitor or a member of the Clergy acting as a sponsor of some kind. Even then it's kind of pushing the boundaries.
One does not simply become a heretic and become forgiven.
Which leads into my question. Why would she have become a heretic in the first place if she was of the high caste of Ishgard in the first place? What is the severity of her crime?
